French Motorail is slashing 10pc off fares for motorists who put their cars on the train this summer in Calais and sleep all the way to the Cote d'Azur - provided they book by June 30.

The cut-price Motorail package also includes a cheap ticket on Eurotunnel - so one-way tickets from the rail terminal in Folkestone, to Brive in the heart of the Dordogne, start at £358 for car and two people. Eurotunnel travellers, however, must book returns to get the cheapest rate. French Motorail information is on 08702 421 415 and www.frenchmotorail.com
